text: Isolation from Streptomyces platensis, PLM is produces. Genes PnT1 and PnT2 regulate the post-synthesis of PLM to form PLM B by the phosphorylation and added the amine group . Figure 4 is based on the biosynthesis analysis on the Gene journal introduced that PLM B is used to produce PLM A, and 4 more PLMs C-F. The PLM A-F are the post synthesis product of the biosynthesis of PLM with the modification of many enzyme PnT1-T8.
  PLMs regulates the actin cytoskeleton as they induce actin depolymerization by the indirect way. In the experiment, PLM F does not affect to the polymerization of purified actin in vitro. However, PLM F enhances the phosphorylation of intracellular vimentin.
